WATER SPRINKLING DEVICE Filed Aug. 21. 192e ssiszfall /WWirT/V Patented June 24, 1930 UNITED STATES GEORGE. A. WILLIAMS, F LOS ANGELES, CALIFORNIA WATER-SPRINKLING DEVICE Application filed August 21, 192B.

My invention relates to a water sprinkling device, particularly of the type disclosed in my copending application for U. S. Letters Patent filed December 6, 1927, Sr. No. 238,-

001, and the principal object of my present invention is to generally improve upon and simplify the construction of the sprinkling device disclosed in my aforesaid patent lapplication, as well as other similar forms of sprinkling devices.

Furtherobjects of my invention are to provide a relatively simple, practical and eihcient sprinkling device that may be utilized as al connecting member between two sections of water conduit such as hose or pipe, thereby enabling a plurality of the devices to be located in a water line so that water may be sprinkled simultaneously on ia lawn or in a garden or orchard, and further 2o to provide a device having a readily adjustable valve for controlling the discharge of water from the jet orifice and, further, to provide simple and efficient means for locking the valve in differently adjusted positions.

A further object of my invention is to provide a water sprinkling device of the character. referred to wherein the central portion of the body of the device through which the valve passes and in which the jet so orice is formed is made sufficiently large to permit the full capacity volume of water to flow through the device and thus eliminate the possibility of cutting down the volume flow of water to the succeeding devices located in a water line, and which action would result in an unequal distribution of the sprinkled water.

Vith the foregoing and other objects in view, myvinvention consists in certain novel features of construction and arrangement of parts that will hereinafter lbe more fully described and claimed and illustrated in the accompanying drawings, in which :Y

Fig.1 is a top plan view of a water sprinkling device embodying the principles of my invention.

F ig. 2 is a vertical longitudinal section on the line 2-2 of Fig. l. r

Fig. 3 is a top plan View of a modified form of the sprinkler.

Serial No. 301,047. Y

Fig. 4 is a vertical section taken on the line 4-4 of Fig. 3.

Referring by numerals to the accompanying drawings which illustrate a practical embodiment of my invention, 10 designates a substantially bowl-shaped body with which is formed integrally a horizontally disposed top plate 11 and formed integrally with and projecting upwardly from the edge of said top plate is a circular flange 12, having a convex inner face 18.

Formed in the center of plate 10 is a jet orifice 14: and formed integral with the top of the plate around this orifice is a short upwardly projecting circular flange 15. rihe upper end of the orifice 14x@y is countersunk as designated by 16 to form an inclined valve seat.

Formed integral with and projecting outwardly from the body of the bowl-shaped member 10 are short tubular extensions 17 to which may be secured in any suitable manner sections 1S of hose or pipe.

Formed integral with and depending from the bottom of the bowl-shaped body 10 is a lug 19 through which is formed a threaded aperture 20 that is in direct alinement with the jet orifice 1e.

Screw seated in the threaded aperture 2() is the threaded lower portion 21 of a valve stem 22, which latter extends through the orifice 14 and formed integral with the upper end of said stem is a head 23 that functions as a valve and the under face of which head is inclined or beveled to correspond with the inclination of the countersunk valve seat 16. The diameter of valve stem 22 is slightly less than Vthe diameter of the orifice 14 and thus when the valve23is slightly elevated with respect tothe seat 16 vwater is free to flow lthrough the oriiice and to discharge upwardly and outwardly through the space between the inclined seat .16 and the correspondingly inclined under face ofv valve 23.

Located on the threaded portion 21 of the i valve stem below the lug 19 is a'nut 241 that functions as a packing member and a lock nut.

/Vhen this lock nut is tightened against the underside of lug 19 it tends to prevent leakage of water through the joint between the threaded portion of the stem and the threaded aperture 2O and said nut, when thus tightened, also locks the valve stem in its adjusted position in the device.

Depending from the lower end of the valve stem is a pin or prong 25 which may be inserted in the ground to anchor the sprinkling device while the same is in use.

The height of the flange 12 is such thai. -its upper end occupies a horizontal plane slightly above the top of valve 23 when the latter is in full open position and thus the valve is, to a certain extent, protected against being struck by extraneous objects while in operation and the inner face 13 of the flange being made convex will not interfere with the outward and upward discharge of water from the inclined space between the flange seat 16 and the head 23 of the valve.

In the modified form of the device illu@- trated in Fig. 3, the bowl-shaped body 10- is devoid of the tubular extensions 17 and projecting outwardly and downwardly from one side of said body is a tubular extension 26 that is externally threaded in order that it may be screwed onto the upper end of supply pipe.

This form of device is intended for use on overhead water supply pipes or for supply pipes that lie beneath or on top of the ground along the edges of walks, driveways or immediately adjacent to a fence or building wall. j

In this construction the valve stem 22a passes through a lug 19a on the bottom of the body 10a and a segment on one side of the valve 23a is cut away in order to provide an arcuate opening between said guideway portion and the valve seat when the valve is positioned upon its seat Aand thus water may discharge through said opening, thereby sprinkling water over the ground on one side only of the device.

The lower portion of the stem 22a is threaded and this threaded portion passes through the lug 19a without being threaded therein, and arranged on said threaded portion below the lug is a packing gasket washer 27 and a nut 28, which latter when tightened draws the valve on the upper end of the stem downwardly onto its seat. Tl: lower end of the stem .22a is provided with a transverse slot 29 for the reception of.a screw driver or like tool, thereby permitting the valve stem to be adjusted from a position beneath the body 10a so as to locate the arcuate outlet opening in differently adjusted positions.

` The valve stems and valves in the two forms of the device herein disclosed may be interchangeably used and if desired an inclined deflector plate of the type disclosed in my aforesaid copending application may be arranged on the top of the bowl-shaped body so as to deflect the water issuing from the jet oriice in any desired direction.

Thus it will be seen that I have provided a lawn sprinkling device that is relatively simple in construction, inexpensive of manufacture, capable of being readily adjusted so as to suit different conditions and require ments, and the stem of the valve that controls the discharge of water through the jetI orifice being provided with simple and eflicient means for locking said stem and its valve in differently adjusted positions.

It will be understood that minor changes in the size, form and construction of the various parts of my improved water sprinkling device may be made and substituted for thosel herein shown 'and described without departing from the spirit of my invention, the scope of which is set forth in thc appended claims.

I claim as my invention:
